Thesis on sound and Design

but that kind of meaning is easily appropriated, so there's no way to argue similarity of intent in sound w/o image. However, the constant association of a sound with an image would tend to create a different, relatively more stable meaning.

This experience can be applied in a commercial sense to make a connection between that feeling and their product.

that's true: think about that car commercial with the Telepopmusik song.

but, now that i think about it, "experimental sound" of that kind is done all the time with Musak.
